Knight’s Armament Barrel Extension Wrench 5.56/7.62

KAC PN 30447

The KAC Barrel Extension Action Wrench is used to securely hold an SR-15 or SR-25 upper receiver in a bench vise so that work may be performed on the muzzle device and/or rail system. It is inserted through the rear of the upper receiver to engage the barrel extension. This tool is compatible with SR-15 E3 and SR-25 Barrel Extensions ONLY. It can be damaged by using it in a standard square lug bolt AR-15 barrel extension.

  1. Rusty Shackleford

    KAC doesn’t make many of these, but buy one when you can. It makes swapping out a muzzle device simple without damaging the very expensive kac upper! These are essential for owners of the sr15 or 25 uppers or rifles.

    My new favorite KAC supplier. The email notification system works. I literally got tracking info within 45min of paying! Got to Alaska extremely fast! They sent me sticky note saying “they understand this addiction is expensive, so we provided a free meal for you” on top a bag of Top Ramen!!

    DA BEST!!
